Overclocking Report and BIOS Walk through

Overclocking Results:
Stock Max. OC
CPU Multiplier: x33 x47
Motherboard BLCK: 1100 MHz

1600 MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

If you were savvy enough to buy an unlocked Intel Core i5 2500K or 2600K CPU from the get-go, you probably already know the unlocked CPU multiplier will let you push these chips into the mid-4 GHz range with little effort. Owing to the integrated graphics on Sandy Bridge processors however, overclocking via the processor BCLK beyond about 105MHz isn't practical.

Gigabyte's GA-Z77X-UD5H-WB motherboard offers up a full range of CPU and IGP overclocking controls in the BIOS and within Windows 7 via TouchBIOS. Since BCLK overclocking is generally limited to 105MHz, PCSTATS left memory settings alone and focused on the CPU multiplier.

Starting from the default x33, PCSTATS pushed the CPU multiplier to x39, x42, x44 and x47 where the system crashed. The Core i5 2500K chip PCSTATS tests with generally maxes out at x47, so that's where our overclocking adventure stopped.

Since the Gigabyte GA-Z77X-UD5H-WB motherboard is equipped with onboard video outputs PCSTATS had a go at overclocking the Intel HD 3000 IGP as well. From the stock IGP speed of 1100MHz, PCSTATS was able to overclock the Intel HD 3000 graphics core to 1600MHz without much difficulty.


Redundant BIOS chips prevent bad BIOS flashes from taking down the board.

Gigabyte's Dual UEFI BIOS

The UEFI '3D BIOS' user interface is intended to help novice PC users interact with complicated BIOS settings on friendlier terms, when you mouse over different bits of the board photograph, like the CPU area, memory or expansion slots, it bring up the relevant UEFI BIOS option menu. Advanced BIOS options are available at the bottom, which is where we'll be focusing our attention.

There are a lot of voltage control options in the GA-Z77X-UD5H-WB BIOS; for memory, chipset, CPU and motherboard VRM. There's also a slew of really advanced voltage controls available via Gigabyte's '3DPower' menu from the Windows desktop.
